Criminal justice client rehabs can be considered as being a significantly better option than incarceration or significant fines for individuals who have been convicted of any kind of alcohol or drug related crime. By way of example, anyone who has been in prison for driving under the influence of drugs or alcohol may qualify to get treatment services for their problem as an alternative to serving time in prison. The judge may even order the individual receive rehabilitation, either alone or as well as other sentencing. First-time offenders specifically tend to be given the opportunity to select a criminal justice client rehab instead of other sentencing, and it is well-advised they reap the benefits of it if it's an option. The theory behind criminal justice client rehabs is it is way more effective and efficient to invest effort and time into treatment than enforcement of other consequences. Much research has been carried out to discover how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following rehabilitation. The signs and indicators seem to be quite positive, and criminal justice clients that do take part in treatment have better potential for remaining out of the system after rehabilitation.
